what generation is MC572LL/A apple tv

In general:

Identify your Apple TV model - Apple Support

Having just entered MC572LL into DuckDuckGo search, that finds:

https://everymac.com/systems/apple/apple-tv/specs/apple-tv-2nd-generation-black-specs.html

Which indicates second-generation.

A second generation which at this point is pretty obsolete, you may want to consider getting an Apple TV HD or Apple TV 4K, both would be major upgrades.

Second.
